Optimizing Soft Speech Recognition in Children With Hearing Loss
Hearing LossSensorineural2 moreOverhearing is important for vocabulary learning and speech and language development in young children. However, contemporary hearing aids are generally unable provide adequate access to low-level auditory inputs from multiple talkers at a distance to capitalize on overhearing. A recent investigation by Jace Wolfe and colleagues showed that, even when aided, children with hearing loss had significantly poorer speech recognition at 40, 50 and 60 dBA compared to children with normal hearing. Furthermore, they showed that increasing hearing aid gain for very low-level inputs produced a statistically significant improvement in syllable-final plural recognition and a non-significant trend toward better monosyllabic word recognition at very low presentation levels. Additional research is needed to document low-level speech recognition ability of children with hearing loss as well as the potential benefit or detriment of increasing hearing aid gain for low-level inputs. A novel hearing aid technology known as Soft Speech Enhancer has been shown improve low-level speech perception in adults with hearing loss; however, the effect of Speech Enhancer on speech recognition in children is not yet known and will be evaluated.
Comparison in New Cochlear Implanted Subjects of a Tonotopy-based Bimodal Fitting With or Without...
Sensorineural Hearing LossBilateralMain objective: For a bimodal fitting (hearing aid (HA) + cochlear implant (CI)): Comparison of a tonotopy based fitting strategy with synchronization between HA and CI (ABFS) to a tonotopy based fitting strategy without synchronization (ABFnoS) for the accuracy of sound localization. Secondary objectives: Comparison of ABFS to ABFnoS for the bias of sound localization. Comparison of ABFS to ABFnoS for speech perception in noise. Comparison of ABFS to ABFnoS for the auditory skills experienced by the subject.

Hearing LossBilateralThe purpose of this exploratory study is to trial various objective and behavioural fitting methods for potential use with Focused Multipolar Stimulation programming.
Multicenter, Prospective Observational Study for Early Diagnosis, and Development of Follow-up Protocol...
Solid TumorChildhoodMore than half of all pediatric cancer in Korea are solid cancer. For the treatment of solid cancer, multidisciplinary methods such as surgery, chemotherapy, and radiation therapy are applied, and with the development of the treatment method, the treatment performance has improved dramatically, and the 5-year survival rate of more than 80% is currently recorded. Due to the improvement in survival rate, interest in side effects caused by cancer treatment itself is gradually increasing, and efforts to reduce them are increasing. Accordingly, it aims to contribute to improving the quality of life of pediatric solid cancer survivors. by developing a Korean-type early diagnosis and follow-up protocol of ototoxic hearing loss, which commonly occurs in pediatric solid cancer who have undergone chemotherapy.
Evaluating Hearing Aid Service Delivery Models
PresbycusisAging1 moreThe purpose of this study is to compare the outcomes for two different hearing-aid delivery models. In one model, the audiologist selects and fits the hearing aid and, in the other model, the consumer does this directly.
The Effect of Sodium Thiosulfate Eardrops on Hearing Loss in Patients Who Receive Cisplatin Therapy...
CancerThis is a pilot, randomized, self-controlled study of the effects of intratympanic sodium thiosulfate (STS) on the degree of hearing loss in patients receiving cisplatin therapy. Sodium thiosulfate is an inactive ingredient contained in sulfacetamide ophthalmic solution which is used routinely as an otic solution delivered to the middle ear space. The hypothesis of this study is that local administration of sodium thiosulfate (STS) will result in improved hearing compared to ears not receiving the study drug in patients receiving systemic cisplatin therapy.

Cochlear Implantation in Single Sided Deafness and Asymmetrical Hearing Loss: a Cost/Utility Study....
Retrocochlear PathologyAuditory Processing Disorder2 moreThe investigators assume that cochlear implants in this indication are not only effective but also cost-effective. The investigators' experimental protocol relies on real life therapeutic strategy, where a cochlear implant may be proposed once CROS and bone conductions systems have failed. Thus, all subjects enrolled in our study will try CROS and bone conduction devices. If these trials are ineffective, the remaining subjects will be randomized between two arms (cochlear implantation vs 6 months abstention followed by cochlear implantation). A comparative cost-utility analysis between the two arms, of medical consequences measured in terms of quality of life will identify a preference for a strategy. Specific binaural hearing measurements with respect to each treatment option (abstention, CROS, bone conduction device, cochlear implant) will also be collected.
Use of Amplification in Children With Unilateral Hearing Loss
Unilateral Hearing LossUnilateral hearing loss (UHL) in children has been demonstrated to have a negative impact on quality of life, school performance and behavior. Despite this knowledge, it remains unclear how to best manage this common problem. There has been much debate regarding this issue with many programs recommending preferential seating in the classroom and use of a frequency-modulated (FM) system to amplify the teacher's voice in the classroom (conventional measures), and others recommending these accommodations in addition to use of a hearing aid for amplification (amplification). There is very limited research to support or refute the efficacy of a hearing aid in improving measurable academic, behavioral, or quality-of-life (QOL) outcomes in children with UHL. We propose a study evaluating the impact of hearing aid use in school-aged children (ages 6-12 years) with mild to moderately severe UHL. In this study, subjects will be randomized to receive either conventional measures or conventional measures plus amplification. After a three month period, the groups will be reversed, with each subject serving as their own control. Outcome measurements will include patient reported disease-specific QOL reported by patients, parents, and teachers using validated survey instruments at regular intervals throughout the study period.
